Buoyancy force come from difference in density of the object and the surrounding.
Buoyancy of the ship can change from the pay load inside its' space. More load per space reduce the buoyancy. For Balloon, buoyancy is change by increase temperature of gas inside to balloon since increase in temperature would cause gas to expand and had lesser density in its' cavity.
In general, buoyancy increase or decrease by changing of density of the object or the surrounding medium.
